This is because a function could have only one output value for each input value. If the vertical line you’ve drawn intersects the graph more than once, the relation plotted on the graph would not be a function. Among different type of data representations possible, the representation which consists of pictures i.e A pictorial representation of data is called pictograph. The y value where this vertical line intersects the graph is known to represent the output for that value of x. Answer :b)the pictorial representation of data is calledpictograph. A vertical line would include all the points that relate to the x values. Using a vertical line test, you can make out whether the graph showcases a function. Graphs could be helpful in identifying whether or not a relation is a function. Also, you already know that the domain and range for it could be identified with the fact that the values for domain are represented on the x axis and the values for the range are represented on the y axis. The different function graphs could be identified by the properties that are exhibited by the graph. Given below are the examples of several other functions and their graphical illustrations. As per this situation, Coordinate axis x = 0 would be regarded as an asymptote to the graph of y = 1/x.
The limiting case for the graph of the function is said to be shown by the asymptote.Īsymptote means the straight line along which the function approaches infinity does not actually touch it as the figure illustrates.
The graph of a function could be helpful in showing various properties of the respective function even more clearly and directly. Suppose that a function f : R – → R has been represented on the coordinate in a way that the x coordinate is known to represent the independent variable and the y coordinate represented the dependent variable. Now when you’re already aware of what are functions, we would straight away move towards its graphical representation.
